My computer 'hard' freezes (i.e., the only way to get out is to do a hard reset by hitting the power switch), where the num/cap/scroll locks keys don't even work. This happens randomly when I browse the Internet on Firefox. It doesn't seem to happen when the PCI Express wireless adapter is disconnected. I am using a TP-Link WDN4800 wireless adapter with whatever default driver is already installed on Linux Mint (I did not install any additional drivers). I added the line

Frankly, I'm not sure whether it is due to my wireless adapter or some kind of Firefox plug-in causing my computer to freeze... but it is definitely related to Internet access since my computer is stable with the wireless adapter removed without Internet access.

Edit: Edit: Never mind. The syslog actually didn't record anything when the system froze.

I had a similar problem the other day. It was similar by the fact I had a "hard" freeze whilst I was browsing with Firefox. I am not aware of the cause, and would like to find out.
I would like to keep an eye on this, to see if there is any resolution.

Oops...forgot to edit my post. It actually happens even when I'm not browsing Firefox. As long as the wireless adapter is plugged into its PCI-express slot, my computer randomly crashes. I checked the memory, power supply, and everything and everything seems to be fine. I am using integrated graphics on my i5 so graphics should not be an issue. I spent too much time trying to solve the issue so I gave up and went back to Ubuntu (with cinnamon) and everything is fine again.

I am still unsure what the problem is though but I am posting an update just in case it might help somebody else...

Hi,
I've installed the new Kernel as you suggested it ans that simply went worse. The boot is slower, i've lost all the wireless settings and other things. How do i get back to the Kernel previously used? and does anyone have other suggestions to solve the freezing issue?
Thanks
